" When he turns inland he sees two moving white columns in the sky. At first glance he thinks they are emissions of smoke. The two encroaching formations ripple into funnels and then spread out beneath the labyrinthine coral of clouds into fans. His vision blurs for a moment. Then he realises he is witnessing two perfectly synchronised flocks of birds. The abstract shapes they form are flawless. He stands with his hands in his pockets as the birds taper into a long undulating line, which gently vanishes behind the surface of things. The same thing has happened to his father. He has vanished behind the surface of things. "
